interspaces much wider. The teeth have stout conic crowns, with well 

 developed cutting edges and coarse striate sculpture. The mandible is 

 acuminate to the narrow extremity, and has a long symphysis which extends 

 to opposite the third tooth behind the notch. The cervical vertebrae preserved 

 have round cups; they have a simple elongate hypapophysis, with a pit 

 behind it ; .•shoulder very prominent.

Portions of a few vertebree are preserved. An anterior cervical has a 

 massive hypapophysis whicli connects the two parapophyses. Its quadrate 

 base is thickened posteriorly ; as the apex is broken off it is impossible to 

 ascertain its length. Immediately behind it on the middle line is a deep 

 fossa like a foramen. On the middle of the posterior shoulder below, is a 

 low, acute tuberosity ; the shoulder is very prominent, and its sides are 

 slightly i-ugose. The cup is subround. A posterior dorsal has a capitular 

 costal surface extending vertically. The cup is a little wider than deep, 

 and the base indicates a strong hypapophysis. The face of the posterior 

 shoulder of another dorsal is much roughened by closely placed ridges and 

 small tubercles.

The skull of the second specimen has a resemblance in general to that 

 of the Crocodilus affinis, but differs materially. The three most prominent 

 points of distinction are the following : There is no distinct transverse ledge 

 of the frontal bone between the orbits, and the space between the anterior 

 parts of the latter is honey-combed like the posterior frontal region, and 

 not smooth. Secondly, the posterior part of the squamosal bone, where it
